How much do you know about Cambridge inventions? Take the quiz to find out.

How many other cities the size of Cambridge lay claim to so many world-changing inventions?

Once called Newtown, the place had a decent shot at becoming the capital of Massachusetts in the 1600s. It lost out to Boston, got a college as a consolation prize, and has been pretty busy ever since.

Two new books out this month make a convincing case that when it comes to science, medicine, technology, literature, and social activism, Cambridge, with a population of about 118,000, has been a major driver of progress.

One is “Born in Cambridge: 400 Years of Ideas and Innovators,” by the husband-and-wife team of Karen Weintraub and Michael Kuchta, and the other is “Where Futures Converge: Kendall Square and the Making of a Global Innovation Hub,” by Bob Buderi. “Born in Cambridge” is a nicely illustrated greatest hits list, geared to history buffs and general readers; “Where Futures Converge” dives into the dynamics that make Kendall Square such a powerful engine of scientific breakthroughs and startup formation.

All three authors live in the city. Weintraub is a former Boston Globe science editor who now writes about health care for USA Today, and Kuchta is an urban design planner at Harvard. Buderi was the founder of the startup news outlet Xconomy, and editor of the MIT-published magazine Technology Review.


Rather than serving up a book review, here’s a 20-question quiz based on the two books. Some questions may even stump people who’ve lived or worked in Cambridge for decades. If you get 15 or more right, you’re a superstar. The answer key is at the end.
